In the most basic model, the seismogram consists of two entities: (1) the pure primary events representing the reflection coefficients of the interfaces and (2) the myriad of multiple reflections. Most of the reflection coefficients for sedimentary layering are small in magnitude. In such cases, the model can be simplified greatly. Specifically, the strongest and most troublesome multiple events can be associated with horizons that have large reflection coefficients. These are called the major interfaces, and the corresponding primaries from these interfaces are called the major reflections.
